Please pardon my ignorance on this one but I purchased an RS6 almost 3 years ago now and I've wondered the entire time whether I want to leave it as is or go for a little more. Problem is, I don't know what I got and neither did the uber-shady dealer I bought it from.

So, how can I tell with things like: is it chipped or have the k04 been swapped for something else? I'm in the middle of fighting the beast so it can pass emissions (EVAP leak and SAI too low) so I can go routing around if need be but I have a VagCom as well so I would like a 5 minute scan type of solution. Beggars can't be choosers, I know but I'm an American, I like convenient (lazy) options.

BTW, 3 years later and I still love the RS6.
